Thiazide diuretic (water tablet)
Brand of Bendroflumethiazide
Last reviewed June 2026
Who is this for?
Bendroflumethiazide is a water tablet (diuretic) that helps your body get rid of extra water and salt through your urine, which helps lower your blood pressure and reduce swelling.
Inhibits sodium and chloride reabsorption in the distal convoluted tubule by blocking the thiazide-sensitive Na⁺-Cl⁻ cotransporter, increasing urinary sodium and water excretion and reducing blood volume and peripheral vascular resistance.

For high blood pressure, the usual adult dose is one 2.5 mg tablet taken once daily in the morning. For swelling, your doctor may start you on 5 mg to 10 mg daily, then reduce the dose once the swelling goes down. Take it in the morning so you are not waking up at night to urinate. You can take it with or without food.
If you miss a dose, take it as soon as you remember — but only if it is still morning. If it is already afternoon or evening, skip the missed dose and take your next dose the following morning. Do not take two tablets at once to make up for it.
Only buy from reputable pharmacies — avoid roadside sellers, as fake or expired water tablets are dangerous. Do not stop taking this medicine suddenly without your doctor's advice, even if you feel fine — high blood pressure often has no symptoms. If you feel very weak or get muscle cramps, see your doctor as your potassium may be too low.
NSAIDs like ibuprofen (commonly sold in Nigeria) can reduce the blood pressure-lowering effect of this drug and may harm your kidneys — avoid regular use together. Digoxin (used for heart problems) becomes more dangerous if bendroflumethiazide lowers your potassium, so your doctor should monitor your blood levels. Alcohol can increase dizziness and the blood pressure drop, so limit or avoid drinking alcohol while on this medicine.
